Yes there are subset of people with visual problems who also have auditory problems, that does not mean you should not support the ones with vision only problems.
Are there not "ML techniques" for visual captchas too ?
With more and more powerful models like GPT-3 coming along every few months, Even if the accuracy levels are less for visual over audio today how long do you think that is going to last ?
I believe they meant that audio captchas have become inaccessible to humans in general. Bots have gotten so good at audio captchas that the difficulty level has to be high enough that humans are also unable to complete them.
Visual captchas too can be quite very hard these days for the same reasons, there are many other ways to verify bot or human, many of them may not allow you to remain anonymous while doing so, pretty much any 2FA method could work for example.
I would say given the choice for a number of people the accessibility is more important than loss of privacy. At least it is choice they should have instead of shutting them off the internet.
Hi HCaptcha-er here. You don't lose all your privacy with our accessibility option. Also we always abide by DNT style protections even for accessibility. That being said our privacy pass solution is totally private and safe.

There are.

I don't know. So far it hasn't been difficult to recognize the garbage traffic when we take the time to look. And attackers always make it easier by releasing github source and / or announcing their results on Twitter.
